Kilayim 3:4 - 3:5

שתי שורות של קשואין שתי שורות של דלועין שתי שורות של פול המצרי מותר – for each two rows appears like a field of its own, and there is recognition and there isn’t confusion here and this where is a furrow that interrupts between each and every species, but one row of cucumbers and one row of gourds and one row of the Egyptian bean is prohibited, even though there is a furrow interrupting between each and every species, because these three species, their leaves spread out and intertwine with each other, but when there isn’t there anything other than one row from each and every species, it appears as if all of them were sown together with one and the same throw, and it appears like Kilayim/mixed seeds, and the interruption of the furrow is not recognized in them.

ושורה של קישואין ר"א מתיר- for he holds that since there are two rows of cucumbers even though they are not adjacent to each other, we consider them as if they are adjacent and here is here a field of cucumbers and a row of gourds and a row of Egyptian bean, it is as if they are planted in a field of cucumbers and it is sufficient for them with the distance of furrow, as it is taught in the Mishnah above (Tractate Kilayim, Chapter 3, Mishnah 3), “that if his field was sown with [one kind of] vegetables, and he wishes o plant a row of another [kind of] vegetables,” etc.

וחכמים אוסרים - because the two rows of cucumbers are not adjacent one to another, they are not considered as a field of cucumbers and appear like Kilayim/mixed seeds, and there is confusion here and there is no interruption of the furrow that would be effective with them. And the Halakha is according to the Sages.

קישות ודלעת – that their leaves spread out and become intertwined with each other and all the more so, the other species.

זו נוטה לצד זה – for even though there Is no interruption of a furrow that is effective for them, the leaning of these leaves (i.e., of the cucumber) to one side and those (i.e., of the gourd) to the other is effective for them, for since that which the Sages forbade regarding Kilayim/mixed seeds they did not prohibit other than because of the sake of appearances.
